Application led July 13, 1918.

T0 all whom t may concern.'

VBe it known that I, DAVID LAMBERT, a citizen of the United States, residing at Cleveland, in the county `of Cuyahoga and State of Ohio, have invented certain new and useful Improvements inMachine-Tools, of which' the following is a specification.

My invention relates to improvements in tools, and more particularly to` combined boring, drilling and milling machines, the machine being particularly designed and adapted for usein boring, drilling and milling capacities. in machine tool work.

The primary object of the invention is to provide a generally improved machine of this class which will be exceedingly simple in construction, cheap of manufacture, and efficient in use.

A. further and very important object of this invention is to provide improved gear and feed control mechanism adjustable and opera-ble from any common and vdesired point by a single operator stationed in suitable proximity to the work carried upon the adjustable platen or table and whereby such single operator may feed all the various working parts either singly or simultaneously, as desired, to meet the varying demands and e'Xigencie's of actual service, the machine being of particular` advantage in large work, or' especially where the work carrying table or platen is somewhat removed or spaced from the main actuating gearing and spindle carrying head of the machine, whereas in machines of this general class or type now in common use two operators are frequently required, one being stationed near the work and the other near the head of the machine to receive instructions from the primary operator, this method of operation resulting in obvious disadvantages .well known to those skilled in the art to which this invention appertains.

Vith the above mentioned and other objects in View, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated inone of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the accompanying drawings, forming a part of this specification. Figure is a front elevation of a machine constructed in accordance with this invention,

- The 'carriage=17,-is provided with aplaten-` g` ortable 26, mounted in'suitable guide'ways onthe .carriagek and adapted :to 'be moved transversely yof the bed and "upon the tableV by means of a screw 27, and as ai means of Vautomatically moving v'such platen or table A 26, .transversely y(as for'exa'mple in milling operations) the screw 27, is .provided with a worm gear 28, V(see Figs. 18 to 22, inclusive)V meshing with a worm V29," carried in a movable box 30, said box 30, being mounted on shaft22, and'said worm 29, being pro- Y vided with a pinion 31, meshing withva y pinion 32, on the 'shaft 22, said pinion 32, being provided wijtha key 32a, arranged to slide in the key way or spline of thefshaftV 22, (see`Fig-.,21). Asa means o fthrowing the worm 29, into zand out ofengagement with Vthe worm gear 28, the lower side ofthe carriage is provided with a shaft 33,'havi'n'g a finger' or'arm 33, in operative contact with the free side of the movable box 30, and actuating the latter in a well known manner through the medium of the handle 33".

`'The driving shaft 22, extends into the. service or distribution box 4, and receives its motion through the medium of a bevel gear 34, meshing with a bevel gear 35, below, and meshing with a Vsecond bevel gear '36, above, (see Fig. 17) the bevel gear 36, being connected to the shaft 16, which extends upwardly through `the gear box 13, and is provided with the worm 15. The bevel gear 35, is connected to a shaft 37, yextending below into the gear box or casing 1c, and receiving its motion from the gearing, as hereinafter deseribed,and the bevel gear 34, is provided witha pinion 38, (see Figs. 17 and 26) meshing with a bevel gear 39, mounted on a transverse horizontally extending shaft 40, said shaft 40, extending rearwardly and being provided with a second bevel gear 41, attached to the vertical screw 3, for elevating and 'depressing the saddle or spindle carrying head 2, hereinbefore referred to.

As a means of throwing the shaft 40, out of engagement with the gears whereby said shaft 40, may be manually operated for the manual raising and lowering of the saddle or head 2, the shaft 40, is provided with a keyed or splined clutch sleeve 42, (see Fig. 26) adapted to bethrown out of engagement with the bevel gear 39, to the dotted line position by means of the shift lever 43.

Referring now to the mechanism for driving the spindle 5, (see Figs, 9, 10 and 11) it will be seen that the vertical driving shaft 6, is provided with a bevel gear 44, .keyed or splinedupon the shaft and arranged within the gear housing 2b, said bevel gear 44, meshing with a second bevel gear 45,'mounted on a horizontal shaft 46, said shaft 46, being provided with ia'gcarfwheel 47, meshing with a second gear-wheel 48, and the gear-wheel 48, `meshing with a gear-wheel 49, on the spindle 5. lThe wheel 49, is splincd upon the spindle 5, so that the latter may be fed forwardly or retracted by the mechanism hereinbefore referred to, and the spindle 5, is rotatably secured to thelongitudinally mov- -able sleeve 7, by being mounted upon a bar 50, the latter being threaded to the end of a second bar `51, rotatably mounted in the sleeve 7, and it willalso be observed upon reference to Fig. 9, of vthe drawings, that the rear end of the spindle 5, and the adjacent or forward end of the sleeves 7, are provided with thrust ball bearings 52. The bar 50, is held in proper relativeposition in the sleeve 7, by means of a collar having a square or angular shaped head, designated by the numeral 51, in Fig. 2, ofthe drawings.

Asa means of enabling the spindle 5, to

be moved manually thc worm gear may be disconnected from the shaft 12, by means of a clutch sleeve 53, (see Fig. 25) operated by means of a shift lever 54, connected to a slide 5-5, it being obvious that when the worm gear is out of engagement with the shaft 12, that the latter may be manually turned 'by means of the armed wheel 56, provided with a bevel gear 57, meshing with a second bevel gear 58, on shaft 12, as shown most clearly in Fig. 25, of the drawings.

Referring now to the changeable gearing within the gear box or casing 1", by means of which motion is imparted to the various pants hereinbefore referred to, it will be seen that one end of the base or bed 1, is provided with a driving shaft 59, provided with a clutch 60, and a pulley 61, said clutch 60, be# ing adapted to be thrown into engagement with the pulley 61, through the medium of a lshift lever 62. l

As a means of transmitting motion to the various parts through the driving shaft 59, the driving shaft 59, in the casing is provided with aflanged longitudinallyshiftable gear 63,'carried by a gear shift tumbler lever 64, and the body of the said tumbler lever is provided with a second gear 65, having a smaller gear a. The gears 65 and 65, are

adapted to be thrown into mesh with a plurality of stepped or graduated gears 66, 66h, and 66, arranged on a second shaft 67, the latter shaft being provided with a pinion 68, at its end. The gear 66", meshes with a gear 69, on a shaft 70, at the rear 0f the gear casing, said shlaft 70, is provided with two bevel gears 71 and 72, loosely mounted thereon within a gear housing 1f, of the machine frame or base, said gears 71 and 72", being adapted to be alternately thrown into operation or engagement 'with the shaft by means of a shiftable splined clutch 73, for the purpose of giving alternate and opposed motion to the bevel gear 74, on the shaft 6, and for the purposes hereinafter referred to. The splined clutch 73, is also mounted in such a manner that when moved to a neuosition, as shown in Fig. 15, of the drawings, it will be out of engagement with the gears 71 and 73, and thus no motion imparted to such gea-rs and the bevel gear 74, and theV shaft to which it is attached.

The pinion GS, on the shaft 67, meshes with a second pinion 75, on a shaft 7 6, and the shaft 76, is provided with a second change gear tumbler lever 77, said second tumbler lever 77, being provided with a pinion 78, splined on the shaft 7 6, the pinion or gear 78, meshing with a second pinion 79, and said second pinion 7 9, being adapted to be selectively brought into mesh with any of the four gears 80, 80, 80", and 80C, on the shaft 81, said shaft 81, being provided with a pinion 82, adapted to mesh with the large gear 83, said gear 83, being provided with the gears 813 and 84, being adapted lto be simultaneously shifted whereby the. large gear 83,`isvbrought out of mesh withthe pin- Yiojii 82, and the small gear S4, is brought4 into -mesh with the gear 80?, or vice versa, by
